My invention relate the term hair bein on the human head,

In the bleaching of hair, it has long been the s to the bleaching of hair, g used herein to mean hair oleaginous solution of an amine, preferably in the presence of supplementary agents, as hereinafter set forth in detail. This oleaginous solution is mixed with an aqueous solution of a practice to employ a peroxide, specifically hydroperoxide, particularly hydrogen peroxide, and gen peroxide. J-In'view of the fact that hydrogen the resulting emulsion or dispersion is applied to peroxide decomposes in an alkaline medium, the the hair relatively promptly or shortly thereregular practice in bleaching the hair has been after. After the bleaching has been completed, to admix aqueous hydrogen peroxide of desired the composition is readily washed from the hair. volume strength with an aqueous solution of 10 The oleaginous material may be of fixed or ammonia immediately prior to application to the volatile character and may be selected from the hair, the ammonia acting to de-stabilize the hygroup consisting of animal, vegetable and mindrogen peroxide and accelerate therelease of eral oils.

In mineral oils, preferably water-white and of a the first place, the bleaching treatment results consistency generally similar to those of the in drying out of the hair and rendering it britmedicinal variety.

in addition, it serves in the role of a solubiliz- 50 ing agent for the composition. Thus, when a solution is made up containing, for example, mineral oil, oleic acid, and monethanolamine substantially in excess of that required to neutralize the oleic acid, the resulting solution is not clear. 65

The addition of a suitable proportion of a higher molecular Weight alcohol, such as lauryl alcohol, serves to render the solution clear or transparent. In general, While the proportion of such alcohol is variable, a satisfactory range is from about to about of the composition. Among the higher molecular weight alcohols which may be utilized may be mentioned, for example, octyl alcohol, nonyl alcohol, decyl alcohol, undecyl alcohol, linoleyl alcohol, stearyl alcohol, ricinoleyl alcohol, palmitoleyl alcohol, lauryl alcohol, myristyl alcohol, cetyl alcohol, oleyl alcohol, melissyl alcohol, ceryl alcohol, carnaubyl alcohol, myricyl alcohol, higher molecular Weight glycols such as cetene glycols and other vicinal glycols, branched chain octyl, decyl, dodecyl, tetra-decyl and octadecyl aliphatic alcohols, as, for example, Z-n butyl octanol-l, 2-butyl tetra decanol-l, and, in general, the higher molecular Weight saturated and unsaturated aliphatic straight chain agmine, 1, hke; and aro rg ene di 22853350 as in and tero amine and th eliVat or yl anljn a cychc bases 511 e a -(filled I h Subst' ut nd 010 ch 01 chaln a1 t ave als 0 10 pr u S an s Whlch h01S, P pe t n esseglggft be highlctsdthere f to the ltiig are tifinf the co s of e 1 so f r a esir and f t of s oc 9 cor 1n t Clea nventi a e C S e broader 5 or hydro Veg t d 1n t rid mg porti 0 a 110118 sol t n of ncerned, to sesame i natecl, a am a1 Orig n e 11 or rsibl ulsifying a t e amine, a 12 D. 011 1 coconut 0 192 tto mural am1 e in t ent wh Is Drof Om n the th1m kernel on laseed 011 utiliz I Vario i s Solut of ave 8 ca 08 alcoh lsoya th 10 ain t 01112341 1 111117.; by 61: e Obt n d 1 ymg ent ma coco eciall em pref ng h hi her plcymg alts o usually atisfact b minant mlxed fatty satisfactory esult acids su cular Weigh soaps of e n 0rd p rti n of 1 ontai In S h olami as than t t lc or fines tion 6 a e fu ul-ryl a ol. g a pre at ylene eats, diet1? eate e 11111 a e m Significance of t he high vrat ang t g mlne lama; 1 preciateil gg es g he fol l m acids Whos ecular i ht, 6 Am is b at t e p 0 rth.

It also oleic acid 30 functions to enhance the wetting action of the Monoethanolamine 22 In use, immediately or shortly prior to the application to the hair, the oleaginous compositions described hereinabove are mixed with aqueous hydrogen peroxide. Thus, for example, one part by volume of the oleaginous preparation may be mixed with from 2 to 5 parts by volume of hydrogen peroxide of 17 to 20 volume strength. A uniform, oleaginous emulsion is produced which is then applied to the hair. The proportions of the oleaginous preparation and the aqueous hydrogen peroxide employed may be varied, depending upon the rapidity of bleaching and the shade desired.

It will be understood, of course, that in all cases there is a suificient content of free amine in the oleaginous solution so that when the latter is mixed with the aqueous hydrogen peroxide or the like the resulting emulsion or dispersion is alkaline in reaction.

As indicated hereinabove, the proportions of the various ingredients are subject to considerable variation. Thus, for example, the oleaginous material may range from 40 to 60 parts by volume, the amine from 10 to 25 parts by volume, the emulsifying agent, when used, 0.5 to 50 parts or and more, and the higher molecular weight alcohol, 7

when used, from about 10 to aboutfio parts by giolume.

Supplemental agents such as perfume and the like may, of course, be added to the composition without in any manner departing from the spirit of the invention as set forth in the appended claims.

Wherever the term higher is used hereinabove and in the claims, as applied to fatty acids, alcohols and the like, it will be understood to mean at least 8 carbon atoms unless otherwise specifically stated.
